IMPROVEMENT IN TABLE FOR CHANGING GAUGE OIE' RAILWAY-CAR TRUCKS.

The Schedule referred to in these Letters Patent andmakng part of thesame.

To all whom 4it may concern:

Be it known that I, GEORGE F. MORSE, of Portland; in the county ofCumberland and State of Maine, have invented a new and useful Table-forChanging Gange of Changeable Gauge Car-Trucks; and 1 do hereby declarethe following to be a full, clear, and exact description thereof', whichwill enable others to make and use myinvention, reference heilig had tothe accompanying drawings forming part of this specication, in which-Figure l is a top plan oi' my invention, showing the table, rails, Ste.

Figure 2 is a vertical end section of the same, arranged for changingfrom narrow to broad.

Figure 3 shows a pair of wheels, in position for changing from broad tonau'ow gauge.

lhe purpose of my invention is to produce au arrangement of devices forthe purpose of changing gauge of changeable gauge car-trucks; and

1t Vconsists in the application of inclined surfaces, whereby the weightofthe car assists in changing the gauge ofthe trucks.

a a, in figs. 1 and 2, and a', in fig. 3, show the tracks upon which thecar is run preparatory to the truck being changed.

These tracks bear upon inclined surfaces, shown by b b, in figs. 1 and2, and b', in fig. 3.

These inclined planes b b b are confined to each pltler, and kept atproper distances apat by the bars lhe tmcks a are kept 1n tuen' properplaces by the screws c c', igs..1, 2, and' 3.

The screws are confined by the stops f f, (figs. 1 and 2,) and in iig. 3the screws are represented as iight and left-hand, connected by a'singlenut, e.

The operation of changing gauge, say from narrow to broad, (see figs. l.and 2,) is as follows:

Thetruck to be changed is run upon the tracks a a, which are then at thehighestpart ot' the incline. The wheels and axles are then prepared forthe change, the wheels being loosened, so as to move freely on theaxles. The tracks c a are then drawn ont by means of' the screws c,bringing with -them the wheels, the weight of the car materiallyassisting in the operation, having a tendency to press the tracksoutward on the inclined surfaces, as well as downward. The stops ffarrest the tracks c a when they havereached the broad gauge. .Lhe truckis then run off' upon the broad-gauge rails.

The operation of changing gauge from broad to narrow is the same inprinciple as that above described, excepting that the inelines arereversed in posit-ion, the tracks moving inward and downward, as shownin tig. 3. In this figure the screw c' is represented as extendingacross the table, between the rails a' a', and

operating in a right and left-hand nut, c.

`What I claim as my invention, and desire to secure by Letters Patent,is-

1. The inclined planes of the tables b b' and tracks a a', as hereinshown, operating asdescribed.

2. In combination with the said inclined planes, the stops f and f'. 3.In combination with Ythe said inclined planes, the screws c and rightand left-hand screwc.
